Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the user does not necessarily park in the guided passenger compartment. The user may try to select the most convenient passenger compartment among the limited available passenger compartments, and the user's trial and error, waiting behavior, etc. have been the causes of congestion in the parking lot. For example, in a parking lot attached to a commercial facility, there is a desire to select a passenger compartment near the elevator. In summer, the passenger compartments on the rooftop floor tend to be avoided. When the user is not used to driving, a passenger compartment where there is less traffic of people and vehicles and where parking can be done calmly is preferred over a popular passenger compartment.

[0006] Therefore, an object of the present invention is to provide a parking lot management server that can generate information for assisting the user's selection while preventing congestion in the parking lot.

Means for Solving the Problem

[0007] The parking lot management server of the present invention includes an available passenger compartment identification unit, an incoming vehicle identification unit, and an incoming vehicle permission number determination unit.

[0008] The available passenger compartment identification unit receives occupancy information and the passenger compartment number or the sensor ID corresponding to the passenger compartment number from each passenger compartment sensor installed in each passenger compartment in the parking lot at predetermined time intervals, and determines that an available passenger compartment has occurred for the passenger compartment number indicating that the occupancy information has remained changed from full occupancy to empty occupancy over a predetermined time, and identifies the available passenger compartment.

[0009] The incoming vehicle identification unit receives an image from a roadway camera that captures a divided roadway obtained by dividing the roadways in the parking lot, and identifies an incoming vehicle that is a vehicle entering each divided roadway.

[0010] The incoming vehicle permission number determination unit determines the incoming vehicle permission number, which is the number of vehicles that may enter a predetermined divided roadway, by subtracting the number of incoming vehicles in the predetermined divided roadway from the number of available passenger compartments in the group of passenger compartments facing the predetermined divided roadway.

Effects of the Invention

[0011] According to the parking lot management server of the present invention, it is possible to generate information that supports the user's selection while preventing congestion in the parking lot.

Modes for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described in detail. Components having the same function are denoted by the same reference numerals, and redundant descriptions are omitted.

Examples

[0014] Hereinafter, explanations of the terms used in the description of Example 1 will be given.

[0015] <Parking Lot Management Server 1> The parking lot management server 1 is a server that manages and controls the parking lot that appears in this embodiment, and is connected to the devices described later via a network. The parking lot management server 1 can be realized by, for example, a general-purpose computer or the like.

[0016] <Vehicle Compartment License Plate Reader 2> The vehicle compartment license plate reader 2 is installed in each vehicle compartment in the parking lot and reads the license plate number of the vehicle parked in the corresponding vehicle compartment. The vehicle compartment license plate reader 2 can be omitted in some cases. The vehicle compartment license plate reader 2 may be able to determine the license plate numbers of multiple vehicle compartments with one unit. For example, a license plate recognition camera or the like may be used as the vehicle compartment license plate reader 2.

[0017] <Vehicle Compartment Sensor 3> The vehicle compartment sensor 3 is installed in each vehicle compartment in the parking lot and transmits occupancy information and the vehicle compartment number (or sensor ID corresponding to the vehicle compartment number) to the parking lot management server 1 at predetermined time intervals. The vehicle compartment sensor 3 may be combined with the vehicle compartment license plate reader 2. It may also be a device that can detect the states of multiple vehicle compartments with one vehicle compartment sensor. For example, sensors such as magnetic type and infrared type, or a camera that recognizes characters and the vehicle may be used as the vehicle compartment sensor 3.

[0018] <Pre-payment Machine 4> The pre-payment machine 4 transmits the license plate number (or parking ticket ID associated with the license plate number) and settlement information indicating the completion of parking fee settlement to the parking lot management server 1 according to the user's parking fee settlement process. For example, the pre-payment machine 4 may read the ID of the parking ticket inserted by the user, inquire about the corresponding license plate number from the parking lot management server 1, and transmit it to the parking lot management server 1 together with the settlement information corresponding to the relevant license plate number. Alternatively, the pre-payment machine 4 may transmit the parking ticket ID and the settlement information corresponding thereto to the parking lot management server 1, and the parking lot management server 1 may associate the license plate number associated with the received parking ticket ID with the received settlement information. The pre-payment machine 4 may be a general pre-payment machine used in the license plate authentication system disclosed in, for example, Reference Non-Patent Document 1.

[0019] (Reference Non-Patent Document 1: "Parking Solutions - Product Services - License Plate Authentication System", Parking Solutions Co., Ltd., <URL:https: / / www.parking-s.co.jp / buisiness / numberplate.html>) The pre-payment machine 4 may be excluded from the components of the parking lot management system of this embodiment in some cases.

[0020] <Gate License Plate Reader 5> The gate license plate reader 5 is installed at the entrance gate of the parking lot and reads the license plate number of the vehicle entering the parking lot. The gate license plate reader 5 transmits the parking ticket ID, which is the ID of the parking ticket issued corresponding to the read license plate number, to the parking lot management server 1. The gate license plate reader 5 may be a device equivalent to a parking ticket issuer used in a license plate authentication system disclosed in, for example, Reference Non-Patent Document 1. The gate license plate reader 5 may be excluded from the constituent elements of the parking lot management system of this embodiment in some cases.

[0021] <Roadway Camera 6> The roadway camera 6 continuously photographs the divided roadways that divide the roadways within the parking lot. The roadway camera 6 transmits the photographed video to the parking lot management server 1. The roadway camera 6 may be a millimeter wave radar.

[0022] <Divided Roadway / Trunk Roadway> The divided roadways are those obtained by dividing (partitioning) the roadways within the parking lot, for example, at intersections, branch points, corners, etc. All the divided roadways may be treated as each divided roadway, but when the divided roadway is an important roadway used by any vehicle or when the divided roadway does not face the passenger compartment, these divided roadways may be defined as trunk roadways and excluded from the divided roadways. As an example of the trunk roadways, trunk roadways 1 to 4 are shown surrounded by dot hatching in FIG. 7.

[0023] Examples of the divided roadways 1 to 3 are shown in the same figure. As shown in the same figure, it is preferable to treat, as divided roadways, the roadways that are not necessarily used by any vehicle and face the passenger compartment, with the adjacent intersections, branch points, and corners as the start and end points of the corresponding divided roadways.

[0024] <Electric Display Board 7> The electro-optical display board 7 is installed at a position visible to the user, such as at the entrance of each divided roadway (see Fig. 7). The electro-optical display board 7 receives display control information, which is information for displaying the permitted number of incoming vehicles, from the parking lot management server 1 and executes a display according to the display control information. The electro-optical display board 7 can be omitted in some cases.

[0025] <Device Configuration of the Parking Lot Management System> As shown in Fig. 1, the parking lot management system of this embodiment includes a parking lot management server 1, an in-vehicle license plate reader 2 (which can be omitted in some cases), an in-vehicle sensor 3, a pre-payment machine 4 (which can be excluded from the system in some cases), a gate license plate reader 5 (which can be excluded from the system in some cases), a roadway camera 6, and an electro-optical display board 7 (which can be omitted in some cases). Details of the devices other than the parking lot management server 1 have already been described.

[0026] <Functional Configuration of the Parking Lot Management Server 1> As shown in Fig. 2, the parking lot management server 1 of this embodiment includes an empty vehicle compartment identification unit 11, an incoming vehicle identification unit 12, and an incoming vehicle permission number determination unit 13. Hereinafter, with reference to Fig. 3, the detailed operations of each functional configuration will be described.

[0027] <Empty Vehicle Compartment Identification Unit 11> The empty vehicle compartment identification unit 11 identifies an empty vehicle compartment by any of the following methods (S11).

[0028] [Identification Method 1] The empty vehicle compartment identification unit 11 receives occupancy information and the vehicle compartment number or the sensor ID corresponding to the vehicle compartment number from each vehicle compartment sensor 3 at predetermined time intervals, and identifies an empty vehicle compartment by considering that an empty vehicle compartment has occurred for the vehicle compartment number indicating that the occupancy information has remained changed from full occupancy to empty occupancy over a predetermined time. When using Identification Method 1, the in-vehicle license plate reader 2 can be omitted, and the pre-payment machine 4 and the gate license plate reader 5 can be excluded from the system.

[0029] [Identification Method 2] As shown in FIG. 4, the vacant passenger compartment identifying unit 11 receives occupancy information, passenger compartment numbers, or sensor IDs corresponding to the passenger compartment numbers from each passenger compartment sensor 3 at predetermined time intervals, receives vehicle numbers and passenger compartment numbers or reader IDs corresponding to the passenger compartment numbers from the passenger compartment vehicle number reader 2, and receives vehicle numbers or parking ticket IDs associated with the vehicle numbers and settlement information from the pre-settlement machine 4. For a passenger compartment number where the occupancy information has remained full to vacant over a predetermined time period, when settlement information has been received for the vehicle number corresponding to the passenger compartment number, it is regarded that a vacant passenger compartment has occurred for the passenger compartment number, and the vacant passenger compartment is identified. When using Identification Method 2, it is necessary to incorporate the passenger compartment vehicle number reader 2, the pre-settlement machine 4, and the gate vehicle number reader 5 into the parking lot management system.

[0030] <Incoming road vehicle identifying unit 12> The incoming road vehicle identifying unit 12 receives images from the road camera 6 and identifies incoming road vehicles, which are vehicles entering each section of the road, by any of the following methods (S12).

[0031] [Identification Method 1] The incoming road vehicle identifying unit 12 regards all vehicles shown in the images received from the road camera 6 as incoming road vehicles. In this method, for the vehicles shown in the images, the outgoing vehicles / incoming vehicles are not distinguished, and all are treated as incoming road vehicles.

[0032] [Identification Method 2] The incoming road vehicle identifying unit 12 may regard, among the vehicles shown in the images received from the road camera 6, the vehicles shown near the corresponding vacant passenger compartment within a predetermined time from the occurrence of the corresponding outgoing vehicle as outgoing vehicles and exclude them from the incoming road vehicles. In this method, for the vehicles shown in the images, the vehicles regarded as outgoing vehicles are excluded, and the other vehicles are treated as incoming road vehicles.

[0033] [Identification Method 3] There is a specific method 3 as a further extension of the specific method 2. As shown in FIG. 5, when a vehicle regarded as a shipping vehicle among the vehicles shown in the video received from the predetermined road camera 6-x1 no longer appears in the video (in the example of this figure, the number of vehicles shown in the video changes from 1 to 0), and the difference between the time when a vehicle starts to appear in the video received from the road camera 6-x2 that captures the section road adjacent to the section road captured by the road camera 6-x1 (in the example of this figure, the number of vehicles shown in the video changes from 0 to 1) is equal to or less than a predetermined threshold, the vehicle that starts to appear in the road camera 6-x2 is continuously tracked as a shipping vehicle and excluded from the incoming vehicles in the adjacent section road.

[0034] ≪When the shipping vehicle cannot be identified≫ For example, as illustrated in FIG. 6, when there is one shipping vehicle shown in the section road captured by the road camera 6-x1 and this shipping vehicle is moving from west to east, and there is one incoming vehicle shown in the section road captured by the road camera 6-x4 and this incoming vehicle is moving from north to south, and a vehicle starts to appear in the road camera 6-x3 that captures the section road adjacent to the east side of the section road captured by the road camera 6-x1, and at the same time, a vehicle starts to appear in the road camera 6-x2 that captures the section road adjacent to the south side of the section road captured by the road camera 6-x4, there is a possibility that it cannot be determined whether the shipping vehicle has proceeded to the side of the road camera 6-x3 or the side of the road camera 6-x2.

[0035] In this case, when it is desired to strictly determine the number of permitted incoming vehicles, all the corresponding vehicles after the inability to discriminate may be treated as incoming vehicles and the tracking may be continued. When it is desired to loosely determine the number of permitted incoming vehicles, all the corresponding vehicles after the inability to discriminate may be treated as shipping vehicles and the tracking may be continued.

[0036] [Specific Method 4] Specific methods 2 and 3 are effective when the vehicle number cannot be identified or tracked on the road. On the other hand, when the resolution of the video of the road camera 6 is sufficient to capture the vehicle's number plate and the parking lot management server 1 can perform vehicle number recognition using the video, specific method 4 is effective. In specific method 4, the incoming vehicle identification unit 12 performs vehicle number recognition on the vehicles shown in the video received from a predetermined road camera 6, tracks the outgoing vehicles based on the recognized vehicle numbers, and excludes the outgoing vehicles being tracked from the incoming vehicles.

[0037] [Specific method 5] When the road camera 6 has a function of recognizing vehicle numbers, specific method 5 is effective. In specific method 5, the incoming vehicle identification unit 12 receives the video from a predetermined road camera 6 and the vehicle number recognition results of the vehicles shown in the video, tracks the outgoing vehicles based on the received vehicle numbers, and excludes the outgoing vehicles being tracked from the incoming vehicles.

[0038] <Incoming permission number determination unit 13> The incoming permission number determination unit 13 determines the incoming permission number, which is the number of vehicles that may enter a predetermined section of the road, by subtracting the number of incoming vehicles in the predetermined section of the road from the number of empty vehicle compartments in the group of vehicle compartments facing the predetermined section of the road (S13).

[0039] At this time, the incoming permission number determination unit 13 may transmit display control information, which is information for displaying the determined incoming permission number, to a predetermined electroluminescent display panel 7, and the electroluminescent display panel 7 may display the incoming permission number. As another pattern, the parking lot management server 1 may transmit information for displaying the determined incoming permission number to a WEB server, and the WEB server may display the incoming permission number on a WEB page.

[0040] ≪Example of incoming permission number when outgoing vehicles are included in incoming vehicles≫ The above [Specific method 1] of the incoming vehicle identification unit 12 corresponds to the method of regarding all the vehicles shown in the video as incoming vehicles. When outgoing vehicles are included in incoming vehicles, the incoming permission number is determined most simply.

[0041] For example, in the passenger compartments facing the sectional track 1 in FIG. 7, there are two empty passenger compartments, and one incoming vehicle (the outgoing vehicle represented by the rectangle with diagonal hatching in the figure) can be confirmed by the track camera 6 that photographs the sectional track 1. Therefore, the permitted number of incoming vehicles is 2 - 1 = 1 vehicle.

[0042] Regarding the sectional track 2 in the figure, there are two empty passenger compartments in the passenger compartment group facing the sectional track 2, and no incoming vehicle is shown in the track camera 6 that photographs the sectional track 2. Therefore, the permitted number of incoming vehicles is 2 - 0 = 2 vehicles.

[0043] Regarding the sectional track 3 in the figure, there is one empty passenger compartment in the passenger compartment group facing the sectional track 3, and one incoming vehicle (the incoming vehicle represented by the white rectangle in the figure) can be confirmed by the track camera 6 that photographs the sectional track 3. Therefore, the permitted number of incoming vehicles is 1 - 1 = 0 vehicles.

[0044] ≪Example of the permitted number of incoming vehicles when the outgoing vehicle is not included in the incoming vehicle≫ The above [Specific Method 2] to [Specific Method 5] of the incoming vehicle identification unit 12 correspond to the method of excluding the outgoing vehicle from the vehicles shown in the video and regarding the vehicles other than the outgoing vehicle as the incoming vehicle.

[0045] For example, in the passenger compartment group facing the sectional track 1 in FIG. 8, there are two empty passenger compartments, and two outgoing vehicles and one incoming vehicle can be confirmed by the track camera 6 that photographs the sectional track 1. The outgoing vehicles are excluded, and the permitted number of incoming vehicles is 2 - 1 = 1 vehicle.

[0046] Regarding the sectional track 2 in the figure, there are two empty passenger compartments in the passenger compartment group facing the sectional track 2, and two outgoing vehicles can be confirmed by the track camera 6 that photographs the sectional track 2. The outgoing vehicles are excluded, and the permitted number of incoming vehicles is 2 - 0 = 2 vehicles.

[0047] Regarding the divided roadway 3 in the figure, there is one empty vehicle compartment in the group of vehicle compartments facing the divided roadway 3, and one outgoing vehicle and one incoming vehicle can be confirmed by the roadway camera 6 that photographs the divided roadway 3. The outgoing vehicle is excluded, and the number of permitted incoming vehicles is 1 - 1 = 0.

[0048] As described above, according to the parking lot management system and the parking lot management server 1 of this embodiment, for each divided roadway, since it is determined to be the number of vehicles that may enter the divided roadway, that is, the number of permitted incoming vehicles, it is possible to generate information that supports the user's selection while preventing congestion in the parking lot.

[0049] In addition, by transmitting display control information, which is information for displaying the number of permitted incoming vehicles, to a predetermined electroluminescent display board 7, it is possible to clearly present information that supports the user's selection and prevent congestion in the parking lot.

[0050] In addition, by regarding all the vehicles shown in the video received from the roadway camera 6 as incoming vehicles, it is possible to determine the number of permitted incoming vehicles in a robust and simple manner against errors.

[0051] In addition, by excluding the outgoing vehicles from the incoming vehicles among the vehicles shown in the video received from the roadway camera 6, it is possible to generate information that conforms to the actual situation of the parking lot, and by using this information, it is possible to further alleviate congestion in the parking lot.

[0052] <Supplementary Note> The device of the present invention has, for example, as a single hardware entity, an input unit to which a keyboard or the like can be connected, an output unit to which a liquid crystal display or the like can be connected, a communication unit to which a communication device (e.g., a communication cable) that can communicate outside the hardware entity can be connected, a CPU (Central Processing Unit, which may be provided with a cache memory, registers, etc.), a memory such as RAM and ROM, an external storage device which is a hard disk, and a bus for connecting these input unit, output unit, communication unit, CPU, RAM, ROM, and external storage device so that data can be exchanged therebetween. Further, if necessary, a device (drive) that can read and write a recording medium such as a CD-ROM may be provided in the hardware entity. Examples of such a physical entity having such hardware resources include general-purpose computers and the like.

[0053] In the external storage device of the hardware entity, programs necessary for realizing the above-described functions and data necessary for the processing of these programs are stored (not limited to the external storage device, for example, the programs may be stored in a read-only storage device such as a ROM). Further, data obtained by the processing of these programs is appropriately stored in a RAM, an external storage device, or the like.

[0054] In the hardware entity, each program stored in the external storage device (or ROM, etc.) and data necessary for the processing of each program are read into the memory as needed and are appropriately interpreted, executed, and processed by the CPU. As a result, the CPU realizes a predetermined function (each component represented as the above-described... unit,... means, etc.).

[0055] The present invention is not limited to the above-described embodiments, and can be appropriately modified without departing from the gist of the present invention. Further, the processing described in the above embodiments may be executed not only in time series according to the described order, but also in parallel or individually according to the processing ability of the device that executes the processing or as necessary.

[0056] As described above, when realizing the processing functions in the hardware entity (the device of the present invention) described in the above embodiment by a computer, the processing content of the functions that the hardware entity should have is described by a program. Then, by executing this program on the computer, the processing functions in the above hardware entity are realized on the computer.

[0057] Each of the various processes described above can be implemented by causing the recording unit 10020 of the computer shown in FIG. 9 to read a program for executing each step of the above method and operating it on the control unit 10010, the input unit 10030, the output unit 10040, etc.

[0058] The program describing this processing content can be recorded on a computer-readable recording medium. As the computer-readable recording medium, for example, any of a magnetic recording device, an optical disk, a magneto-optical recording medium, a semiconductor memory, etc. may be used. Specifically, for example, as the magnetic recording device, a hard disk device, a flexible disk, a magnetic tape, etc., as the optical disk, a DVD (Digital Versatile Disc), a DVD-RAM (Random Access Memory), a CD-ROM (Compact Disc Read Only Memory), a CD-R (Recordable) / RW (ReWritable), etc., as the magneto-optical recording medium, an MO (Magneto-Optical disc), etc., and as the semiconductor memory, an EEP-ROM (Electrically Erasable and Programmable-Read Only Memory), etc. can be used.

[0059] Also, the distribution of this program is performed, for example, by selling, transferring, lending, etc. a portable recording medium such as a DVD or a CD-ROM on which the program is recorded. Further, it is also possible to adopt a configuration in which this program is stored in the storage device of a server computer and transferred from the server computer to other computers via a network to distribute this program.

[0060] A computer that executes such a program first stores, for example, a program recorded on a portable recording medium or a program transferred from a server computer, once, in its own storage device. Then, at the time of executing processing, this computer reads the program stored in its own recording medium and executes processing according to the read program. Also, as another execution form of this program, it is also possible that the computer directly reads the program from the portable recording medium and executes processing according to the program. Furthermore, each time a program is transferred from the server computer to this computer, it is also possible to sequentially execute processing according to the received program. Also, it is also possible to adopt a configuration in which the above-described processing is executed by a so-called ASP (Application Service Provider) type service that realizes a processing function only by an execution instruction and result acquisition without transferring the program from the server computer to this computer. Note that the program in this embodiment includes information used for processing by an electronic computer and equivalent to the program (data having a property of defining the processing of the computer but not being a direct instruction to the computer).

[0061] Also, in this embodiment, by causing a predetermined program to be executed on a computer, a hardware entity is configured, but at least a part of these processing contents may be realized hardware-wise.
